The Flyover™QSFP28 demonstration confirms 28 Gbps performance on all four links, with zero bit errors, after having traveled over 16” (40.64 cm) of twinax cable. This demo shows the variety of Samtec interconnects supporting the Xilinx® Virtex® UltraScale+ FPGA VCU118 Development Kit. Included in the kit is an FMC+ Active Loopback Card, which carries Samtec’s direct attach Flyover™ QSFP28.

This loopback mezzanine card was designed to be used in conjunction with the Xilinx UltraScale+ VCU118 development board, and is included in the VCU118 Development Kit. This kit is obviously available from Xilinx.

Credo / Samtec 50 Gbps Backplane Cable Assembly Demonstration

Routing signals through lossy PCBs, vias and other components has become one of the most complex challenges designers face. Samtec’s Backplane Cable Assemblies break the constraints of traditional backplane designs resulting in a cost-effective, high-performance answer to the challenges of 5o Gbps-PAM4 bandwidths. The combination of Credo’s 50 Gbps PAM4 CDRs with Samtec’s ExaMAX® Backplane Cable Assemblies provide an ideal proof-of-concept for long reach signals over cabled backplanes.
